基于SoPC的微小型组合导航系统设计

Design of micro integrated navigation system based on SoPC

针对目前常用组合导航系统由于体积大,造价昂贵,无法进行广泛推广的情况,设计基于MEMS的捷联式惯性导航系统与全球定位系统GPS、电子罗盘EC相融合的微小型组合导航系统。系统以NiosⅡ处理器和Altera公司提供的IP核为基础,建立基于So PC系统的组合导航硬件平台,同时,采用松组合导航信息融合算法,完成微小型组合导航系统运算及软件设计。试验结果有效验证了该文算法的有效性和可行性。

Since the commonly-used integrated navigation system has large volume and high cost,and is unable to be widely popularized,the micro integrated navigation system was designed,which combines MEMS-based strapdown inertial navigation system with global positioning system（GPS）and electronic compass（EC）. On the basis of Nios Ⅱ processor and IP core made by Altera Corporation,the integrated navigation hardware platform based on So PC system was established. The loosely-integrated navigation information fusion algorithm is used to accomplish the operation and software design of the micro integrated navigation system. The feasibility and effectiveness of the algorithm were effectively verified by test results.
